Check connection and IPs of a host.

check_conn.sh

#!/bin/bash

status_conn=$(wget -q --spider http://google.com && echo 0 || echo 1)

	if [ $status_conn -eq 1  ]
	then
	    printf "\n \e[36m Your Internet is pretty much dead!\n  Check your networks...\e[0m\n\n";
	elif [ $status_conn -eq 0 ]
	then
	    external=$(dig +short myip.opendns.com @resolver1.opendns.com);
	    locally=$(ip addr | grep -v inet6 | grep inet | awk '{print $2}'|cut -d"/" -f1 | tail -n1 | head -n2);
	    printf "\n \e[4mExternal\e[0m IP:\t\e[1m\e[32m$external\e[0m\n \e[4mLocal\e[0m IP:\t$locally\n\n";

You can run it directly using curl:

bash <(GET https://gist.githubusercontent.com/MarcelFox/ccd5c0313984ae98a3d435a3a6ed5e79/raw/97b7af7945b12871dcbba90608534311eb50ed28/check_conn.sh)

You must install the proper 'dnsutils' package on your distribution in order to run dig.
